The functions in the upper section are also provided in the Search submenu:
•
Max Search sets the active marker to the absolute maximum in the search range.
•
Min Search sets the active marker to the absolute minimum in the search range.
•
Next Peak sets the active marker to the next maximum or minimum in the search range,
depending on the current search criterion.
The following functions use the stimulus value of the active marker to define the sweep range:
•
Center = Marker sets the center of the sweep range equal to the marker value.
•
Start = Marker sets the beginning of the sweep range equal to the marker value.
•
Stop = Marker sets the end of the sweep range equal to the marker value.
•
Span = Marker sets the span of the sweep range equal to the active delta marker value.
The following functions use the response value of the active marker to scale the y-axis of the diagram :
•
Ref. Value = Marker sets the reference value equal to the marker value.
•
Max = Marker sets the upper edge of the diagram equal to the marker value.
•
Min = Marker sets the lower edge of the diagram equal to the marker value.
•
Zero Delay at Marker corrects the measurement result by adding or subtracting a constant
group delay.
Center = Marker
Sets the center of the sweep range equal to the stimulus value of the active marker, leaving the span
unchanged. The active marker appears in the center of the diagram.
